. or included within the scope of the appended claims.

In the annexed drawings 1- Fig. 1 is a perspective view of a garage constructed in accordance with my invention.

Fig. 2 is a detail view in perspective of a roof slab and portions of the vertical slabs separated from one another.

Fig. 3 is a detail View in perspectiveof a portion of the foundation and an adjacent portion of a side wall.

For the side-walls, roof and floor slabs when the building has floors, I employ units that consist of each of a slab of dimensions that may be easily handled which are formed of plastic fire-proof material and which are moulded by suitable machinery at the point most convenient for the purpose so that the Work of erection is merely placing units in position to form the Walls, roof and floors which Work. or at least for the most part calls for no skilled labor.

The side walls are composed each of two lines of slabs spaced apart one being the exterior and the other the interior of the wall so thatan air space is provided and these slabs I are of similar dimensions but preferably of different materials, the outside slabs belng of concrete and theinsi'de of gypsum, the

concrete being preferable to gypsum because of its Weather resisting properties and the gypsum beingpreferable to. the concrete for the inside walls for its insulating properties because it makes a satisfactory finish and is lighter than concrete." The slabs are stood on end side by side upon a foundation or base of hollow blocks, 10, the outer concrete slabs 11 having at their lowerends rods, 11 embedded therein which protrude I enough to enter a substantial distanceinto the holes in the foundation blocks and the gypsum slabs, v12, having similar rods, 13, which also enter the block holes so" that when grout is poured in the block holes tofill the far same the slabs and foundation blocks will be firmly tied together. At the upper ends the vertical slabs, 11, and 12, have respectively similar projecting rods, 1 and 15, which pass through holes, 16, provided in the roof slabs, 17, which roof slabs are ribbed or corrugated on their upper sides to receive a cement finish, 18, that is floated upon the roof slabs and filling the holes therein around the rods or dowel pins of the wall slabs and covering such rods effects the tieing together of the roof slabs and the wall slabs. The ce-' ment cover floated over the roof slabs has its top surface given the proper pitch or-slope to shed Water. c

The vertical sides of the wall slabs, 11, are reversely rabbeted, the rabbet being of a depth corresponding with the flange 19 produced thereby so that the sides of adjacent slabs overlap and form a joint by which the slabs mutually support one another and which is rendered sufiiciently water-proof by the application of a cement or mortar to the outer portion of the joint.

It will be seen that the work of erection of a building in accordance with my invention may be very easily and inexpensively done because of the form of joint provided pin and cement filled opening connection between the side walls and foundation or v base and the roof slabs.

composed of slabs placed side by side and overlapping one another at the sides, a base composed of blocks with openings, dowels embedded in the slabs and extending into the opening, a cement filling in such openings, a roof slab having openings above the tops of the side walls, dowels projecting into such openings, and a cement cover for the roof slabs filling such openings.
